Please Follow The Finger Circumference Measuring Method Below
Tools needed: a strip of paper or thin string, a pen, and a ruler
Wrap the paper strip around the widest part of the finger you plan to wear the ring on.
Mark the point where the ends of the paper meet.
Remove the strip, lay it flat, and measure the distance between the marks with a ruler – this is your finger circumference.
(Body weight is for reference only – please rely on your actual measurement.)
